    I have been using tomato-K26USB-NVRAM64K-1.28.0503.6MIPSR2Toastman-RT-N-VLAN-Ext for a few weeks now and have noticed that websites are slow to load and names are slow to resolve. This is true for both wireless connections and wired connections. Downgrading to tomato-K26USB-NVRAM64K-1.28.0503.5MIPSR2Toastman-RT-N-VLAN-Ext has restored the snappy internet connection.

    Per the changelog, the only differences between .5 and .6 are:
    Can others confirm the slowdown under .6 or is it just me?

    Actually, now that you bring it up, I think I've noticed a slowdown too.

    Are any of you using IPv6? If so, I'd recommend providing:

    1. Model of router,
    2. Exact firmware being used (filename please, not what's in About)
    3. System uptime (uptime command via CLI, or Status / Overview / Uptime field in GUI)
    4. What type of connection you're using on your local network (ex. wired or wireless); I often have to throw out wireless-based results because of how variable wireless is in latency

    And do:

    5. Disable IPv6 via Basic / IPv6 -- I recommend doing Save + rebooting, not just doing Save then using the router
    6. See if the performance problem remains after reaching an uptime that matches that in #3

    I also had this problem on Linksys e2000 + TWC service. They have no IPV6 here. Had reset, re-flashed, and erased all data in NVRAM memory in case the first one was bad but had same results. Also downgraded to 1.28.7503.5 version. It was tomato-E2000-NVRAM60K-1.28.7503.6MIPSR2Toastman-RT-Std.bin, had issues on both ethernet and wireless.

    I have an RT-N16 running tomato-K26USB-1.28.7503.6MIPSR2Toastman-RT-VPN.
    I have comcast, but do not have IPv6 enabled.

    I'll throw in my own two cents, although I have not been experiencing any problems:

    1. Asus RT-N16 (H/W rev A1)
    2. tomato-K26USB-1.28.0503.6MIPSR2Toastman-RT-N-Ext.trx
    3. 16 days, 04:05:30 (last rebooted to upgrade from .5 to .6)
    4. Ethernet, although I do use wireless for my work laptop (RD'ing from LAN system to it) and my Kindle Paperwhite
    5. IPv6 is disabled (ISP is Comcast)
    6. n/a -- I haven't been encountering any speed issues.

    Possibly what everyone here has been experiencing are the repeated DDoS attacks going across the United States for the past, oh, 2 weeks or so? In case you think I'm kidding:

    These have all been mostly NTP amplification attacks, accomplished by spoofing source addresses of public NTP servers which are misconfigured to allow queries from the public Internet (i.e. spoof source address of a victim, send an NTP packet to said NTP server, response packet from NTP server goes back to victim and overwhelms numerous links).

    Wow, that's a clever way to reach a large group of people. Possibly explains a few things...

    Off-topic question: Were you involved in FreeBSD's fix for this? Just curious, since you're an NTP guru and BSD guy.

    You might want to check your Ethernet driver settings, specifically if any "Green" settings are enabled. I noticed a slowdown as well and realized I did update my Realtek Ethernet drivers and settings reverted to the default settings. Browsing returned to normal after changing some of the driver settings ....

    Far, far from an NTP guru (there's a lot about the protocol I don't know); I just happen to be the guy at my workplace who, repeatedly, has gotten "stuck" dealing with NTP-related problems that all stem from misconfigurations (and the irony is that we actually purchased stratum 1 GPS-based time devices for our datacenters to help ensure proper time sync). But true, I am a BSD guy (1997 to present), but I left contributing to the project some time ago (I do still send PRs (problem reports) though).

    I wasn't involved in FreeBSD's fix; instead most of the community went around and informed distros/vendors of bad defaults. I should also point out that the fix on FreeBSD isn't FreeBSD-specific; it's more to do with the version of ntpd used by FreeBSD. If they were to upgrade ntpd, some of those defaults would need to be adjusted. I didn't know that myself until someone over on the mailing list pointed me to it (as well as others).

    1. RT-N66U
    2. tomato-K26USB-NVRAM64K-1.28.0503.6MIPSR2Toastman-RT-N-VLAN-Ext
    3. Uptime is <1 h to exhibit this behavior
    4. Both wired and wireless
    5. IPv6 has always been disabled

    If I revert to tomato-K26USB-NVRAM64K-1.28.0503.5MIPSR2Toastman-RT-N-VLAN-Ext the problem goes away. I was thinking it is unique to something in the .6 release.

    After upgrading to .7, I do not experience the slow downs. According to the readme, the only differences are:
    February 21 2014 - 1.28.7503.7 and variants

    - webui: h.count isn't set on Last24 page - use the updateMaxL
    value if h.count isn't set - thanks to RMerlin
    - dnsmasq latest - includes upstream changes up to 21/2/2014
    Thanks to Kevin and Simon!
